The active weather pattern continues as we track a weak wave of low pressure associated with a digging trough over the East. This low will bring rain and snow to portions of this region Thursday into Friday. This snow will not be significant at all–only a few inches at most of snowfall is forecast across the Appalachians into portions of New England.

On Thursday, rain showers will break out across the Appalachian mountain chain and surrounding areas from western Pennsylvania through northern Georgia and into the Tennessee Valley. Not much moisture will work into this system, so precipitation for the most part will be light. By the end of the day, the rain may changeover to snow in the western Ohio River Valley as well as in western Pennsylvania and New York, Upstate New York, and the higher elevations of West Virginia.




Overnight Thursday, cold air will move further south and east, allowing for more of the rain to changeover to snow behind the cold front. During the first half of Thursday night, a light to moderate snow is forecast from central New England and Upstate New York down through all of the Appalachians and as far south as potentially extreme northern Georgia and eastern Tennessee. Even Nashville may experience a brief period of snow, but thankfully little to no snow accumulation is expected in and around the city. While the rain showers move into portions of the Southeast, Mid-Atlantic, and southern New England overnight, those showers will also changeover to snow by early-Friday morning across southern New England and portions of the Mid-Atlantic. This snow is expected to fall as far south as the Washington, D.C. area. The U.S. Capital has had a tough time getting accumulating snow and really any snow so far this season, and this event will be no different. Maybe a coating falls in the city, but this snow will only last for a few hours at most.

By Friday morning, the wave of low pressure will already have moved offshore and the trough digs further. Therefore, most of the rain and snow will come to an end by sunrise, although a few lingering rain showers are still possible along the immediate East Coast as well as snow showers in southeastern New England.




Again, snowfall totals will be light with this event, but some travel issues will still occur during the Friday morning commute based on the timing of this snow and the potential flash freeze that occurs, which is when the rain falls and eventually turns into ice. Here is our snowfall accumulation forecast:
